I thought it’s about time I wrote about the GLP-1 jab i.e. Mounjaro and Ozempic.
I think for some people this is finally the answer to their lifelong fight with their weight. For some people they really can not control what they eat and have yo yo dieted all their life – is this you?
Some of you may have friends or family on it and may want to know more about it. So here we go…..
What exactly are the GLP-1 jabs?
GLP‑1 jabs are medications that mimic a natural hormone in the body called GLP‑1 (glucagon‑like peptide‑1). This hormone helps regulate appetite, digestion, and blood sugar.
How they work (in simple terms)
- Reduce appetite – They slow stomach emptying and help you feel full sooner and for longer.
- Lower cravings – They act on the brain’s appetite centres, reducing the urge to snack or overeat.
- Support blood sugar control – They help the body release insulin more effectively after meals.
Benefits people often experience
- Weight loss due to reduced appetite and lower calorie intake
- Improved blood sugar levels
- Lower risk of overeating or binge‑eating patterns
- Better metabolic health overall
These effects make GLP‑1 meds helpful for people managing weight or certain metabolic conditions.
How GLP‑1 jabs affect Bone Health
This is the part many people don’t hear about.
Why bone health matters
When people lose weight quickly—no matter the method—they often lose muscle and bone density along with fat. GLP‑1 meds can contribute to this because they reduce appetite so much that people may eat less protein and move less.
Potential impacts on bone health
- Lower calorie intake can reduce nutrients needed for strong bones.
- Loss of muscle mass can reduce the mechanical load that keeps bones strong.
- Rapid weight loss is linked to reduced bone density in general.
This doesn’t mean GLP‑1 jabs are harmful to bones, but it does mean people need to be proactive about protecting their strength.
Why exercise & strength training are essential
If someone is using GLP‑1 medication—or planning to come off it—exercise becomes even more important.
Anyone on or coming off the jab really need to think about their lifestyle and HOW they can start incorporating exercise in their life.
Strength training helps by:
- Maintaining muscle mass (which naturally declines with weight loss & also naturally with age, especially post menopause)
- Protecting bone density through load‑bearing movement
- Improving metabolism, making it easier to maintain weight after stopping the medication
- Supporting balance and reducing injury risk
Cardio helps by:
- Supporting heart health
- Improving mood and energy
- Helping maintain weight loss long‑term
But strength training is the non‑negotiable piece for bone and muscle health.
Why exercise matters even more when coming off GLP‑1 jabs
When people stop or reduce GLP‑1 meds, appetite often returns to normal and sometimes stronger than before. Without muscle mass to support metabolism, people are prone to putting on even more weight again.
Strength training helps by:
- Keeping metabolism higher
- Reducing the amount of weight regained
- Helping maintain the healthier habits built during treatment
Simple takeaway points
- GLP‑1 jabs help reduce appetite and support weight loss.
- Rapid weight loss can reduce muscle and bone density.
- Strength training is essential to protect bones and maintain muscle.
- Exercise makes it easier to keep weight off after stopping the medication.
- People need to change their lifestyle to move more and introduce more exercise to their life.
- Think of GLP‑1 as a tool—not the whole solution. Movement and strength are the foundation.
